Today, we are going to discuss the "Role of drawings and awareness of draftersA note about "". I recently gave a stern reminder of the role of drawings and the awareness that drafters should have for the young and new people with whom they work.
To be precise, I scolded him. I will try to summarize how that happened and the story that follows.
Role of Drawings
Left undone (output not checked)
Mechanical design work is very difficult.Recently, I was working on a large project, supporting everyone during the day to ensure that no design mistakes were made, and inspecting the submitted drawings at night.
As we proceeded with the inspection drawings, there were many cases where we forgot to include dimensions.However, in my opinion, I don't consider it a terrible mistake at this point, because forgetting to include the dimensions is only a problem if they were included before the drawings went out to the outside world.
It was worse than that.The layout of the drawings is a total mess."The thing is that it was.
In short, the first thing to think about when starting to draw a parts drawing is the layout of the drawing before adding dimensions, such as "How can I make this easier to see? or "How can I make it easier to see the shape?With a layout that clearly does not consider this,There were many drawings whose shapes were difficult to recognize at a quick glance.
That caused a lot of re-drawing of parts drawings. Too many to count.And all of this was done in the middle of the night. The deadline was right around the corner, so there was no time to say, "Okay, let's fix this," and have it redone the next day.Some of the drawings could be understood if they were enlarged, and some could be understood if one took the time to look at them.However, knowing the best layout and not wanting to miss it, I started over.
The role of drawings and the draftsman's awareness of the role of drawings were conveyed.
We then decided to share those contents with everyone.
Drawings before and after improvement What do you think of these?
Not at all.
People aren't doing what they should be doing before adding dimensions. The drawings need to be drawings that even an idiot can understand. It's not easy to grasp the shape, and it's hard for the person making the drawings.
Also, with all this redoing, do you understand that the work everyone else did was doing work that didn't make sense?
And there's no money involved in redoing it...
And.
Role of Drawings
I understand that design work is not for everyone and is difficult.
Even a single drawing can take many forms and expressions. What is certain is that drawings are a means of communicating to others, and it is one thing to understand them, and quite another to not understand them.There is something I am aware of regarding the role of drawings.The "drawing" that I am aware of each time is, in a word, "a drawing that even an idiot can understand.(It was mentioned in the previous sentence...)
Now,I write "even an idiot can figure it out" without fear of misunderstanding, but I believe that a drawing must be communicated in such a simple way.
That drawing is going to be used by a lot of people.A drawing is an important thing that determines future possibilities. How much future efficiency can be achieved in a mere minute of thinking about a layout?If it is so simple and easy to understand that anyone can figure it out, the time spent looking at the drawings of the people involved may be a short time individually, but collectively it can be quite effective.It is not good if you see it simply as drawing.So I told everyone afterwards.
Review the drawing to see if it really speaks for itself.It is.
The important thing is to change your perspective.
I know everyone is watching (and getting serious).But it is very important to review the work you are doing, because if this is the result, you are doing something meaningless.
Specific ways to do this are,Output on paper, marker check, check the next day.Such as.This may be considered "normal" by veterans, but young people are surprisingly unaware of it. If the reason is that paper is too valuable, they will say, "If you say so, don't do this job.
Here are my musings on such a situation

All right! I'm done!" You don't have to inspect the drawings right after you finish them, but after you have a cup of tea at a fashionable café, you can inspect the drawings objectively.
You can notice things you forgot to do, things that don't feel right, and make new discoveries. That "self-discovery" experience is necessary for a designer. You can freely take time for that.
But I think so.I am not perfect, but this is a gateway to success.
The important thing is to realize it yourself.
Scene of efforts after scolding
You barked. Half of my heart was saying, "I don't care if they don't like me. I might not be able to enjoy drinking with everyone.However, improvements have since been seen.In addition to the "beautiful layout" that I see when I open the drawings and poof,
- Separate display for hidden lines and areas where it is easier to see without them.
- Putting that shape dimension in a direction that is easy to understand of the shape.
- Appropriate graphic frames are utilized for the parts.
- Supplementary notes are provided for the parts that are difficult to understand.
The drawing was quickly changed to something like this.Of course, there are some stable dimension omissions, but I saw them and I was the one who made the draftsman's
- What we want to tell you
- What we want to express
I could intuitively understand what was going on. Therefore, I did not scold them for missing a dimension, but simply said, "If you want to express it this way, you should do it this way,The quality of the pointers has improved.
Finally.
No one likes to tell people what they don't like, but I don't know if my feelings were conveyed to them or if they were just pissed off and did their best, but I was touched to see a little bit of thoughtfulness in their drawings.I also experienced the effects of courageous scolding and took a step forward.
The Role of Drawings and Draftsman Awareness. To all the young people who say they are not good at drafting, make your drawings "drawings that even an idiot can understand! and rethink your own drawings.
That's it.
